Dynamic modeling is a common tool for evaluation of plant operating conditions and control strategies. It can be used during design, prior to start-up, campaign changes, normal plant operation and prior to shutdown to understand the performance. It prepare design and operator to understand the potential problem and get ready to handle and manage the situation.
The following tutorial presents the development approach of dynamic simulation using Hysys which based on implementing three conventional PID control loops (Level, Pressure and Temperature) on a distillation column unit for a binary mixture.
